Identify a transformation of the function f(x) = x2 by observing the equation of the function g(x) = (x + 80)2
answer

In order to transform

You have to apply the transformation

These kind of transformation, i.e.

result in a horizontal translation, k units to the left if k is positive, k units to the right if k is negative.

In this case, k=80, so the graph of

Will be the same of

except for a translation of 80 units to the left.

linear pair postulates

you already gave the answer
